MOUNT VERNON, Va. (Oct. 13) -- Forget what you think George Washington looked like -- that familiar face on the dollar bill -- because he didn't. In fact, the Father of Our Country was not always well served by his portraitists (or his dentists).

This becomes all the more apparent after a visit to the new Mount Vernon museum and visitors' orientation center, which opens Oct. 27 at the first president's 18th-century estate in the Virginia countryside south of the national capital named for him. It's the first major expansion of Mount Vernon in more than 140 years.
